Art+Auction’s editor at large explored the fair in search of a few extraordinary works. His finds included the beautiful/disturbing sculptural objects of Claire Morgan, in which nature meets humanity, at Karsten Greve Gallery; a wartime Wilfredo Lam painting in unsually good condition at Mary-Anne Martin Fine Art; and a menacing and portentous pre-war work by Picasso at Acquavella, on offer for $9.2 million.
